Title: Process for the manufacture of foamed products from granular thermoplastic plastic, in particular granular polystyrene, containing blowing agent
IPC: C08J9/22
Filed: 1961-11-03
Abstract: A process for the manufacture of foamed products from granular thermoplastic plastic containing blowing agent, especially granular polystyrene, which is prefoamed by supplying heat and, after storage, is bonded in moulds by supplying heat once more, is characterized in that granular plastic is employed which is provided prior to the prefoaming operation with a coating impermeable to the blowing agent at the temperatures occurring during conveyance or storage of the granular material. The material used for coating may be one which is burst or rendered permeable in the prefoaming or may alternatively be such that diffusion of the foaming agent is also prevented during the prefoaming.  A coating which becomes adhesive at the temperature used in the moulding (to act as a bonding layer between the particles), or is decomposed by moisture, or is hardened by the application of heat can also be used.  In the examples the granules used are of polystyrene containing dichlorodifluoromethane as blowing agent and coated with (1) polyvinyl acetate and hardener; (2) and (3) polyvinyl acetate in various amounts; (4) methyl cellulose and carboxymethyl cellulose. Alginate and gum arabic are also mentioned as coating materials.ALSO:A granular thermoplastic synthetic polymer containing a blowing p  agent, for use in the manufacture of foamed products, is provided (prior to prefoaming) with a coating impermeable to the blowing agent at the temperatures occurring during storage or conveyance of the granular material.

Abstract: 1,048,330. Rotary-piston internal combustion engines. YANMAR DIESEL ENGINE CO. Ltd. Sept. 30, 1964, No. 39816/64. Heading F1F. To provide better temperature distribution around the periphery of the centre housing portion of a rotary-piston I.C. engine having an inner wall of epitrochoidal bi-arcuate profile co-operable with the corners of a three sided eccentrically mounted piston, a cooling water inlet is provided in the high temperature region of the periphery and partition means adjacent the low temperature region to prevent overcooling. As shown in Fig. 2, a centre housing portion 1 including a gas-mixture suction port 7, an exhaust port 8 and an ignition plug 20 includes a cooling water inlet 3 in the high temperature region A of the inner wall adjacent the ignition plug location where the explosion takes place. In the low temperature region B of the upper wall, i.e. in the region of the suction chamber, a partition wall 5 is formed in the centre housing portion rather nearer to the inner wall so that the major portion of the cooling water passes outside the partition before leaving through the outlet port 6 and has little effect in cooling the inner wall. In another embodiment, Fig. 4 (not shown), the inlet 3 includes a partition to divert a small portion of the water towards the low temperature region. In this embodiment, ribs 10, 11 extending alternately from opposite ends of the housing in the hot temperature region provide a tortuous path for the water to improve cooling of that region. In a further embodiment, Fig. 7 (not shown), the cold temperature region is aircooled and a cooling water outlet surrounds the exhaust port, additional to the cooling water outlet 6. In a still further embodiment a separate chamber is formed adjacent the low temperature region through which cooling fluid, e.g., lubricating oil, which is somewhat warmer circulates. The inner wall of the centre housing alternatively in the low temperature region may have radial axially-extending rib to prevent the cooling water actually contacting the inner wall of the housing.

A dust-carrying gas stream is discharged from the beaded end of a tube 1 and a thin wall layer of the same gas is supplied through annular slot 15, this layer rotating about the tube axis just upstream of the end 3, whereby the main stream is deflected sharply round the beaded end 3 and the dust, being denser than the gas, carries straight on by its own inertia. Annular slot 15 opens into annular chamber 13, to which either gas is supplied tangentially (Fig. 1, not shown), or the supply connection is axial, as shown, and chamber 13 has vanes 18 to induce the rotation. A second chamber 12 with axial supply 16 and annular slot 14 may provide a non-rotating layer of the gas between the main stream and the rotating layer. In Fig. 3, (not shown), a jacket connected to a suction device surrounds and opens adjacent to the end of tube 1, to draw the deflected gas stream away, while the deflection is assisted by a small jet of gas directed towards the said end. The quantities of gas discharged from the slots and in the jet are 5-20% of the main stream, but their velocities are greater.

Abstract: 1280568 Spot-type disc brakes; squealpreventing KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHO 26 Aug 1970 [1 Sept 1969] 40966/70 Heading F2E A disc brake comprises a disc 10, Figs. 4 and 5, a caliper 30, a piston 70 operated by hydraulic fluid (introduced, e.g., at 20) in a cylinder 31 secured to the caliper 30, a friction pad 50 held within the caliper, at least one sealing member 71 between the cylinder wall and the piston, and at least one piston-supporting member 61 made of resilient metallic material, also between the cylinder wall and the piston, the supporting member serving to restrain radial movement of the piston while permitting axial sliding of it, so as to restrict coupled vibration of piston and pad, and thereby reduce brake squeal. As shown in Figs. 4 and 5, each of two opposed cylinders 31 has an internal groove 40 in which is located a helical spring ring 61, Fig. 7. Preferably the outer diameter of the coils of the ring is slightly less than the width of groove 40, but slightly greater than the depth of groove 40, so that the spring protrudes from the groove to engage the side wall of the piston 70. The cylinders form part of a fixed caliper which includes connecting portions 30; hydraulic fluid is introduced to chamber 92 at 20, 21, Fig. 4, and a return spring 95, Fig. 5, is provided. A friction pad assembly 50 may be associated with each piston 70 by locating the lower end of a groove 54 in the pad on a crosshead 77 on the piston, and the lower end of a slot 53 in the back plate 51 on a piston projection 76 (with which the crosshead 77 is integral, Fig. 5), and thereafter sliding the pad assembly downwards to the position shown in Fig. 5. The pad assemblies on opposite sides of the disc 10 may then be secured by locating an inverted U-member 34 on a bridge 33 and securing it in place by bolt 36 and nut 35. The pads are retained by outwardlybent portions 37 of the member 34. Figs. 8 and 10 show a pair of half-circular (see Fig. 10) channel-section piston-supporting members 62 in each of two axially-spaced grooves 40; each pair of such members corresponds to a helical spring ring such as 61, Fig. 5. Instead of a groove, an enlarged stepped bore at the open end of the cylinder bore may accommodate the piston-supporting member. The groove(s) may be provided in the piston instead of the cylinder. The metallic material of the member may be sintered and oil-impregnated.

[Also in Division C7]  A minor proportion (0À5%) of Ni or Ti is added to A1 required to be deposited on selected areas of a semi-conductor body by the technique of covering an extended area with the deposited A1 and subsequently etching it away from all but the selected areas using a photographic resist mask. It is stated that the presence of Ni or Ti in the Al both increases the etching rate of the Al during the production process and also improves the electrical performance of the resulting semi-conductor device. Devices to which electrode contacts can be made in this manner include planar diodes and transistors, integrated circuits, and field effect transistors. Fig. 2 (not shown) depicts an apparatus for depositing Ni-doped A1 on to a semi-conductor. This consists of an evacuated chamber with a tantalum holder for the semi-conductor (e.g. a surface oxidized silicon wafer containing a plurality of semi-conductor components only the contact areas of which are exposed through apertures in the oxide), a vaporization source consisting of an electrically heated body of Al-Ni alloy containing 0À5% Ni, and an iris diaphragm between them. After deposition of 0À5Á of metal on the oxide masked semiconductor surface, the wafer is removed from the apparatus and selectively etched using a photo lithographic technique to remove the deposited metal from all but the required electrode areas. This residual metal may subsequently be alloyed to the underlying semi-conductor.
